What Is This Tool?
This converter transforms values measured in calorie (th)/hour, a unit of thermal power, into ton (refrigeration), a unit commonly used to express cooling capacity in HVAC and refrigeration systems. It facilitates the comparison between small-scale heat transfer and larger-scale cooling rates.
How to Use This Tool?
-
Enter the value in calorie (th)/hour you want to convert
-
Select calorie (th)/hour as the original unit and ton (refrigeration) as the target unit
-
Click convert to get the equivalent cooling capacity in ton (refrigeration)
Key Features
-
Converts calorie (th)/hour to ton (refrigeration) based on defined standards
-
Browser-based and simple to operate
-
Useful for HVAC, refrigeration, and laboratory calorimetry applications
-
Supports translation of thermal power units across different measurement scales
Examples
-
10,000 cal (th)/h converts to approximately 0.0033 ton (refrigeration)
-
1,000,000 cal (th)/h converts to about 0.33 ton (refrigeration)
Common Use Cases
-
Reporting small heat-transfer rates in laboratory calorimetry experiments
-
Expressing metabolic or physiological heat production in thermal power units
-
Sizing and specifying HVAC and refrigeration equipment cooling capacity
-
Performing building energy management and HVAC load calculations
Tips & Best Practices
-
Ensure consistent unit use to avoid conversion errors
-
Use scientific notation when handling very small conversion values
-
Cross-check conversions when integrating device-level data with HVAC system ratings
Limitations
-
Calorie (th)/hour measures extremely small power rates compared to tons of refrigeration
-
Converted values can be very small fractions requiring careful numerical handling
-
Accuracy depends on precise heat transfer definitions and consistent use of units
Frequently Asked Questions
-
What does calorie (th)/hour measure?
-
Calorie (th)/hour measures the rate of heat transfer equal to one thermochemical calorie delivered per hour, quantifying thermal power.
-
What is a ton (refrigeration)?
-
A ton (refrigeration) is a unit of power representing the cooling rate needed to melt one short ton of ice over 24 hours, commonly used to rate HVAC and refrigeration equipment.
-
Why convert from calorie (th)/hour to ton (refrigeration)?
-
Conversion helps translate small-scale heat transfer data from laboratory or device measurements into cooling capacity units used in HVAC and refrigeration design.
Key Terminology
